“When a high-profile Catholic congressman is mangling church teachings, that should be challenged,” John Gehring, Catholic Outreach Coordinator for Faith in Public Life, the organization that put together the statement, told POLITICO.

In an interview with the Christian Broadcasting Network released Tuesday, Ryan said that his religious convictions influenced his budget plan, claiming that the proposal reflects Catholic teachings of local control and concern for the poor.

“[T]he preferential option for the poor, which is one of the primary tenets of Catholic social teaching, means don’t keep people poor, don’t make people dependent on government so that they stay stuck at their station in life, help people get out of poverty out onto life of independence,” said Ryan.

But some Catholic leaders disagree strenuously that Ryan’s policies represent their faith.

“If Rep. Ryan thinks a budget that takes food and health care away from millions of vulnerable people upholds Catholic values, then he also probably believes Jesus was a tea partier who lectured the poor to stop being so lazy and work harder,” said Gehring. “This budget turns centuries of Catholic social teaching on its head. These Catholic leaders and many Catholics in the pews are tired of faith being misused to bless an immoral agenda.”

“Simply put, this budget is morally indefensible and betrays Catholic principles of solidarity, just taxation and a commitment to the common good. A budget that turns its back on the hungry, the elderly and the sick while giving more tax breaks to the wealthiest few can’t be justified in Christian terms,” argue the signatories.

The signatories include the leadership team of the Sisters of Mercy of the Americas, a women’s Catholic organization, a retired Priest in Ryan’s district, and the former Associate General Secretary of the U.S. Conference of Catholic Bishops.

In 2011, after Ryan’s last budget proposal, the president of the U.S. Conference of Catholic Bishops, Timothy Dolan, wrote a letter that — to some social justice advocates in the Catholic community — was insufficiently critical.

Dolan did not endorse Ryan’s plan, but did not condemn it either, commending the Wisconsin Republicans’ “continued attention” to Catholic social justice “in the current delicate budget considerations in Congress,” and praising his attention to fiscal responsibility, the role of the family, the dignity of human life and attention to the poor.
